ACTIVITY OF MINERALIZATION AND HUMIFICATION PROCESSES IN HIGH-FERTILITY DERNO-PODZOLIC SANDY-LOAM SOIL DEPENDING ON THE FERTILIZER APPLICATION

Abstract

The changes of biochemical indices of mineralization and humification of organic substances in high-fertility derno-podzolic sandy-loam soil depending on the application of different fertilizer systems were established using the data on the activity of cellulolytic and amylolytic microbial communities, as well as the results of enzymatic soil diagnostics (hydrolytic and oxidative enzymes). The application of N90+30P15K30 was shown to provide high and sustainable crop yields under a moderate level of organic substances mineralization in С and N-circles.
